System 76 has been doing open source right for quite some time now, and it's just unleashed what it claims is the "most powerfull Ubuntu laptop in the world" -- so powerful it needs that extra L. It's the Serval Professional, offering your choice of Intel Core i7 processors ranging from the 2GHz 2630QM to the 2.5GHz 2920XM. Graphics are handled by a NVIDIA GeForce GTX 485M GPU that pumps 1080p worth of pixel dust to a 15.6-inch, LED-backlit display. Prices for that machine start at $1,379 but you're only a few mouse clicks away from three times that. On the slightly lower-end scale is the Gazelle Professional, with a more limited range of processors and graphics options, but the same 15.6-inch display and a price that starts at $1,239. Both come with any operating system you like -- so long as it's Ubuntu 10.10 Maverick Meerkat.
